Application filed May 1,

To all whom it may concern:

Be it known that I, CLIFFORD C. BROWN, a citizen of the United States, residing at Gartersville, in the county of Bartow and State of Georgia, have invented certain new and useful Improvements in Tension Mechanism for Spoolers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in tension devices for spoolers, and more particularly to the type providing for the endwise discharge of yarn from a bobbin.

The general ob ect in view is the facilitat ing of the transfer of yarn from bobbins to spools while insuring against the delivery to the spool of any slubs or gouts with the yarn; and a more detail object is the accomplishment of this result by apparatus of increased capacity for speed and increased facility for access to moving parts.

A still further object is the construction of such a tension device in a manner enabling its application to the traverse of a spool winding. machine either in the form of a single bar or a series of sections so constructed that when the traverse is once set it will not require resetting.

With these and further objects in view as will in part hereinafter become apparent and in part be stated, the invention comprises certain novel constructions, combinations and arrangements of parts as subsequently specified and claimed.

In the accompanying drawings,-

Figure 2 is a front elevation of the parts seen in Figure 1.

Figure 3 is a plan view thereof, parts be ing omitted.

the usual grooved driving pulley 2 engaged and actuated by the cable 3 in the usual manner from a source of power not illustrated. There are as many of the spindles 1 as there are spools to be wound, each spool being mounted, as seen at 4, on the upper portion of the spindle. Outward or in front of the line of spools 4 is arranged a rail or bar 5 which may be a continuous bar extending throughout the length of the machine in front of all of the spools or may be made in sections as preferred. Whether made inone piece or in sections, the bar 5 is connected by arms 6 to the builder motion of the machine, not shown, whereby the bar 5 is caused to travel up and down in the well known fashion of builder motions and the traverse thereof is adjusted according to the thickness of the yarn and speed of the spools so asto build yarn fed across the bar 5 onto the several spools i. Beneath the bar' 5 and slightly outward therefrom is a, rail 7 which is provided with a series of upstanding studs 8, each relatively short and each adapt ed to sustain a bobbin such as indicated at 9, the location of the rail 7 being such as to U cause the axis of the bobbin to extend in a line approximately flush with the outer edge of the bar 5. There are as many studs 8 as spindles 1, and for each stud 8 there is pro-- vided on the bar 5 a tension mechanism to receive and guide the yarn from therespective bobbin 9. As each of these tension mechanisms is a duplicate of all the rest, only one will be described in detail and that description will be applicable to all. It is important to note that each of the tension mechanisms, as clearly seen in Figure 3, while arranged immediately above the respective bobbin 9 is disposed laterally of the space between two of the spools & so that yarn passing from the bobbin 9 through the given tension mechanism passes on an incline, which for the sake of convenience will be called rearward, to the spool l to which it is being fed.

Each of the said tension mechanisms consists of a disc 10 mounted on the upper surface of the bar 5 and provided with restrain ing means, a yarn approach, and means for clearing foreign substances. The disc 10 is centrally apertured and a pin 11 snugly fits in the aperture of the disc and is provided with a head for enabling the pin to be suspended through the disc with the head resting on its upper surface. The bar 5 is proeas est-a iaa amainai sl t 12, or a wiaal apprd'iiimately equal to the diameter of the -'pi.n 11 and permitting the pin to extend fed -;f;rom its respective siti ft 1gh th'efplaite '5 for. enabling discharge libsfgotitsand other foreign matter.

small quantity of yarn alrea'dy on the spool which is mounted on the spindle 1. The operator grasps the yarn from the spool and drawing it across and a-bove the bar 5 ties it to the yarn from the bobbin 9. He then drops the yarn across the bar 5 in front of the tension mechanism and the yarn immediately threads itself into place by dropping into the slot 16and moving under disc 10 until it contacts with .pin 11 where it continues to feed to the spool. I 1 his automatic "threading of the yarn is incident tothe 1-11 of the spool on the yarn from the 'bo b at an incline relative to the tension mechanism, which .pull results in itheballooning of the yarn as it comes on of the bobbin, un- WiIiC ing therefrom clockwise.

It is to be noted that the stu'ds8 are relabins and for enabling more ready access to the pulleys 2 and 'the adjacent parts.

I The disc -10'fu1'1'ctions not on'lyto tension the yarn and to remove large l'foreign articles, but also because of its revolving motion removes the specks on the y arn that frequently ,pass the knife type of catcher and the location of the. recess or aperture is such that the revolving disc will continue to clear itself and discharge foreign substances down through the bar?) so that there will be no accumulation. but if .a large body of dirt or foreign matter, such as lint, should collect in contact with the disc, so as to interfere with its eifect-ive "functioning, the revolving motion ofthe disc will either clear away such foreign substance or cause the disc and pin to move forwardly infthe slot 12 until such. collection isdischarged. Immediately after'such discharge, the parts willinove back 'to their normal position. The location of the slot 16, and.ipartjcularly its inner terminus, is important in that the angle presented by the slot immediately be neath the :periphery of the disc will insure the removal of gouts and slubs from the yarn by the co operation of theino-ning edge of the disc with the stationary edge of the slot. In every instance, the slub or other objectionable matter will either 'be sheared off or the yarn will be bro'ken. The relative location of each tension 1nechanisin with respect to its 061 causes the yarnto exert a constant jpu l on 'the fp'in'Tl in a direction toward the rear end er the and disc in "proper operative position and to return the same to such position in the event of such extraordinary action as above stated when a collection of foreign sub stances causes the pin to move forwardly in the slot for clearing the disc.
